TUBING HOLDER.

Application led October 18, 1926, Serial No. 142,210. Renewed April 8,1928.

This invention relates to new and useful improvements in a tubingholder.`

One object of the invention is to provide a tubing holder embodying anadapter de- 5 signed to be mounted on a casing head and a tubing slip`adapted to be inserted into said adapter around the tubing to be held. v

Another object of the invention is to provide, in a device of thecharacter described, a plurality of.m

jaws are mounted whereby'the jaws may be conveniently handled.

W'ith the above and other objects in View the invention has particularrelation to eertain novel features of construction, operation andarrangement of parts, an example of which is given in this specificationand illustrated in the accompanying drawings, wherein Figure 1 shows aplan View of the apparatus.-

Figure 2 shows a side elevation thereof. Figure 3 shows a\ verticalsectional view taken on the line 3-3 of Figure 1.

Figure 4 shows a fragmentary longitudinal sectional view of one of theslip handles, and

' Figure 5 shows a fragmentary vertical ure 1. v

Referring now more particularly to the drawings, wherein like numeralsof .reference designate similar parts in each of the figures, thenumeral 1 .designates a, well casing having the casing head 2, ofconventional construction, secured thereon. pump is attached to thelower end of the pump tubing 3, and is let down into the casing and inlowering said tubing, or in with` drawing it,'the tubing holderhereinafter described, is employed. The numeral 4 designates theadapter, as a whole. This adapter is'formed of two sections 5, 6,preferably arcuate in form, and whose'abutting ends are formed, one witha vertical dovetailed tenons 7, 7, which fit into mortises 8,"

v 8, of the other section, land the respective sections are formed withvthe outwardly turned end flange 9, the bolts v10, 10. This adapter ismounted on the casing head and secured thereon in any lsuitable mannerand is formed with the downwardly converging seat 11, adapted to receivethe tubing slip.

readily conform themselves sectional view taken on theline 5 5 of Fig-The 9, secured together by' This tubing slip is composed of the verticalconfronting clamps 12, 12, which are hinged together at one end, as at13, and whose other ends are 'outwardly turned and formed into thehandles 14, 15. The undersides of the clamps 12 are formed with thearcuate grooves Y16, 16, which are contracted downwardly and 'each clamp12 carries plurality of depending tubing engaging jaws 1T, whose outersides taper taper of the seat 11 and whose inner sides are toothed so asto readily engage the tubing The upper ends of these jaws 17 are formedwith the tenons 18, whiclrare fitted into the grooves 16 and areretained therein bymeans of set screws, as v19, which are screweddownwardly through the clamps to eonform'to the l2, and Whose lower endspiojectl loosely into the'oblong recesses 20 in the upper sides of thetenons 18. The jaws are thus swung from the clamps 12 and have fi'eedoinof movement within a restricted rangeso as to to the tubing to be heldby them.

The free end of the handle 15 is bifurcated, and mounted between thelingers thereof there is a swivel block 21 having 'the square bearing 22therethrough through which the rod 23 slides. The inner end of this rodnormally projects into the socket 24, of. t-he handle 15 and has a stop25 secured thereon and interposed between this stop and block 21, andsurrounding the rod 23 is a coil spring 26. The outer end of the rod 23has a suitable eye 27. The free end 0f the handle 14 is provided with atransverse slot 28 and when itis desired to secure. the slip around thetubing 3 the handles 14, 15, are swung together and the rod 23 is', thenpulled outwardly and swung around with the block 21 and its outer end isengagedthrough the slot 28, the eye 27 forniing means for preventing thedisengagement of the handle 14 from said rod 23. The slips may thus beconveniently secured around the pump tubing'and will sustain the tubingsuspended in the well casing'and if in handling the tubing it should beelevated so as to lift the slips out of the adapter, said slips will notrelease the tubing, but when the tubing is again lowered they will seatin the adapter and prevent the tubing from dropping on down into thebore.

los`

henv it is ldesired to release ythe tubing the handles 14, 15, may beunlatched and the swung open,

' cluding ana tubing slip77 elevated` to clear the'adapter and then ingon the top` of the adapter. .The adapter is provided with an` outwardlyinclined inverted U-shaped rest 29 against which lthe slip,when infopenposition, may rest, so as to hold it out of the way of the work, and yetin readiness at all times to be applied around the tubing whennecessary.

What I claim'is:

- l. A device of the adapter having an upwardly iiared opening, a tubingslip adapted to seat in said opening and an upstanding membeil carriedby the adapter andV disposed to one side of said opening and'independentof the slip -but formlng a rest for said slip tohold it in convenientposition for seating' the same in said opening?. y

2. In a device of the character described, slip including confrontingclamps hinged together at one end, outwardly extendingthandles lcarriedby the other ends of said clamps, the under sides of the clamps havingarcuate mortises, tubing engaging jawsA having tenons on their upper enwhich work loosely in said mortises and having their lower ends free andradially movab e.

3. In a device o f the character described, a tubing slip includingconfronting clamps hi togetherat one end, outwardly exnled ten 'nghandles. carried by theother ends the lower ends of the jaws rest.

character. described '1nvyieldable connection yswinging from said ofsaid clamps, the under sides of the -clamps havin arcuate mortises,tubing engaging jaws aving tenons on their up r en which work loosely insaid-mortlses Said jaws depending from said clamps and having theirlower ends free and radially movkfree end of one handle having atransverse slot, a latch rod having a swiveling and a `with theotherhandle and adapted to be en aged through said slot to secure said handes clamps and having their lower ends free.

5. A tubing slip 'including a` sitel'y disposed clamps hinge one end,outwardly extending handles carried by the other ends of the clamps, the

free end of one handle having a transverse a latch rod having aswiveling and a. ds yieldable connection with the other handle slot,

and adapted to be engaged through said slot to secure said handlestogether and tubing engaging jaws depending from said clamps and havingtheir lower ends free.

.In testimony whereof I have signed my mme.
